Effectiveness of Innovative Educational Methods in Empowering Children With Sickle Cell Disease

Sickle-cell disease (SCD) is a genetic disorder that affects hemoglobin, the molecule in red blood cells responsible for carrying oxygen. The disease causes red blood cells to become rigid and sickle-shaped, leading to blockages in blood flow and subsequent pain and organ damage (World Health Organization (WHO),2025). Patients with sickle cell disease suffer from various complications of the disease during their lifetime, including anemia, sickle cell crises, acute chest syndrome, stroke, renal failure, retinal detachment and priapism. However, unforeseen and chronic pain crisis are the most common symptoms reported by the patients which are considered as the most common causes of referral to the emergency department and hospital to receive medical care in sickle cell patients (Poku, Atkin,\& Kirk,.2023). Objective(s) of the study: 1. To evaluate the effectiveness of Innovative Educational Methods on self-efficacy in children with sickle cell anemia. 2. To evaluate the effectiveness of Innovative Educational Methods on self-care capacity in children with sickle cell anemia. 3. To find out the relationship between the effectiveness of Innovative Educational Methods on self-efficacy, self-care capacity and demographic characteristics of children with sickle cell anemia.

Buprenorphine for the Management of Pain in Children With Sickle Cell Disease

The goal of this clinical trial is to learn whether a single dose of buccal buprenorphine (BELBUCA) is safe when used in place and/or with full agonist opioids that would otherwise be started during a sickle cell pain crisis admission, in adolescents and young adults (ages 12-22) with sickle cell disease (SCD) who are hospitalized for acute pain. The main questions it aims to answer are: * Is a single dose of buccal buprenorphine, given at doses between 75 and 450 micrograms, safe in this population? * Does buccal buprenorphine reduce the amount of full agonist opioid pain medicine participants need through their patient-controlled analgesia (PCA) pump, and does it change pain scores? * Are participants and their care team satisfied with pain management when buccal buprenorphine is used? * What are the pharmacokinetic properties (how the body absorbs, distributes, and clears the drug) of buccal buprenorphine in this age group? This is a single-arm, open-label, dose-escalation study: every participant receives buccal buprenorphine, and there is no placebo or separate comparison group. Instead, researchers will compare each participant's own opioid use and pain scores in the 8 hours before receiving buccal buprenorphine to the 8 hours afterward, to see whether the dose reduces the need for additional opioid pain medicine. Participants will: * Be treated first with standard-of-care patient-controlled analgesia (PCA) pain medicine (hydromorphone) during the early, acute-stabilization phase of their hospital stay. * Once their pain is stable and they meet criteria to transition to oral opioids, as would happen under usual care, they will receive a single dose of buccal buprenorphine instead, at a dose (75, 150, 300, or 450 micrograms) assigned according to a dose-escalation design. * Continue to have access to demand-only PCA pain medicine for breakthrough pain after the study dose. * Undergo continuous monitoring of heart rate, oxygen level, and carbon dioxide level, plus pain and sedation checks every 4 hours, for 48 hours after the dose. * Have blood samples collected, only when blood is already being drawn for clinical care, to help study how the body processes the drug. * Complete a brief satisfaction survey about their pain management after the dose. * Be contacted by phone or telehealth, and have their medical record reviewed, 30 days after the dose to check for any safety concerns.

Promoting Utilization and Safety of Hydroxyurea Using Precision in Africa

Sickle cell anemia (SCA) is among the world's most common and devastating blood disorders, affecting more than 300,000 newborns per year. Most infants with SCA are born in the low-resource settings of sub- Saharan Africa, where an estimated 50-90% will die before 5 years of age due to lack of early diagnosis and appropriate care. Hydroxyurea is a safe and effective once-daily oral medication that has become the standard of care for the treatment of children with SCA in high-resource settings. There is now a growing body of evidence to support the safety and clinical benefits of hydroxyurea for the treatment of SCA in sub-Saharan Africa. The requirement for frequent laboratory monitoring, uncertainties about appropriate, most effective dosing, and the concern for hematologic laboratory toxicities, however, will continue to limit widespread hydroxyurea utilization and real-world effectiveness. The investigators have recently developed and prospectively evaluated an individualized, pharmacokinetics-guided hydroxyurea dosing strategy for children with SCA that has demonstrated optimal clinical and laboratory benefits with minimal toxicity. In this research study, the investigators aim to extend this precision medicine approach to Africa.

Hypoxic Red Blood Cells in Sickle Cell Anemia

The overall objective of this study is to evaluate the effectiveness and safety of transfusing hypoxic red blood cells manufactured with the Hemanext ONE system in patients with sickle cell anemia. The Hemanext ONE device was cleared through the De Novo process in September 2023.

Stroke Prevention With Hydroxyurea Enabled Through Research and Education (SPHERE)

This study will 1) Evaluate the prevalence of elevated (conditional or abnormal) transcranial Doppler (TCD) velocities in a cross-sectional analysis of children with Sickle Cell Anemia (SCA) living in Tanzania; 2) Obtain longitudinal data on TCD velocities in this population; and 3) Measure the effects of hydroxyurea therapy on TCD velocities and associated primary stroke risk.

Low Systemic/High Local Exercise Load in Peds SCD

This research study wants to learn about what kind of exercise is best for kids with sickle cell disease. Participating children will have a small amount of blood drawn one time at the beginning of the study. Children will then complete some questionnaires that measure pain, physical function, and emotions (depression, anxiety) and complete some tests that measure physical fitness at the beginning and end of the study. Children will be randomized to either a home-based telehealth (1) walking or (2) strengthening exercise program that lasts for 8-weeks, 3-x week, for 45 minutes each session. Children's participation will last up to 10 weeks.
